When a certain node generates new service or transaction data, the logic storage management module 30 of the node screens out the logic storage module 40 meeting the condition according to the fast storage method of the invention, forms a preselected storage module set for storing the service or transaction data of the node, and sends the IP address, the data address and the Hash value of the data content in the logic storage module 40 meeting the condition to the authentication module 20, the authentication module 20 verifies the information of the preselected storage module set according to the fast storage method of the invention on one hand, and sends the IP address, the data address and the Hash value of the data content of the verified logic storage module 40 to the block 10, the block 10 stores the received IP address, the data address and the Hash value of the data content of the data storage module 40 into the block to be a pointer of the service or transaction data storage address, broadcasting the pointer information of the service or transaction data storage address to all blocks 10 in the block chain system for storage; on the other hand, the information of the verified logical storage module 40 is sent to the logical storage management module 30, and the logical storage management module 30 stores the business or transaction data in all the verified logical storage modules 40, so that one-time data storage is completed.
When a certain node of the blockchain system initiates a data reading request, the node firstly broadcasts the data reading request to all the blocks 10 of the blockchain system, and after all the blocks 10 are judged by a consensus mechanism, a storage address pointer of target data is obtained, wherein the consensus mechanism is judged to be the prior art and is not described herein. The node initiating the data reading request sends the consensus storage address pointer to the authentication module 20, after receiving the consensus storage address pointer, the authentication module 20 confirms whether a record of the consensus storage address pointer exists in a history record, after authentication, the consensus storage address pointer information is forwarded to the logic storage management module 30, the logic storage management module 30 reads service and transaction information data from all authenticated logic storage modules 40 according to the address and sends the read data to the authentication module 20, the authentication module 20 performs consensus judgment on the received data, and sends consensus result data to the node initiating the request.
As an embodiment of the present invention, assuming that the whole blockchain system has n nodes, when node a of the blockchain system initiates a data read request, node a broadcasts the data read request to other (n-1) blocks, so that n nodes in the whole blockchain system all obtain a message that node a needs to read service data. All nodes find the storage address pointer of the target service data from the block of the nodes, and then judge the storage address pointer through a consensus mechanism, for example, the invention adopts a 51% principle that n nodes are used for storing the storage address of the target service dataVoting the pointers, and if the target service data storage address pointers in the nodes exceeding 51% multiplied by n are consistent, considering the target service data storage address pointers as final target data storage address pointers, and recording the final target service data storage address pointers as Adr*. Node A will Adr*Sending to the authentication module 20 in the node a, the authentication module 20 first searches from its history whether there is Adr*If there is no Adr*If so, terminating the data reading request; if Adr is confirmed*If the record is authenticated, the authentication module 20 will add*Sending the data to a logic storage management module 30, reading service and transaction information data from all authenticated logic storage modules 40 by the logic storage management module 30 according to addresses, if the number of the authenticated logic storage modules 40 is m, reading m service and transaction information data by the logic storage management module 30, sending the m data to an authentication module 20, and performing consensus confirmation on the m data by the authentication module 20, which is taken as an example, a principle of 51% is still used here, that is, when 51% x m data are consistent, the obtained consistent data is considered to be the consensus service and transaction information data, and sending the consensus service and transaction information data to a node initiating a request by the authentication module 20, so that the node initiating the request can obtain the requested data.
